10.5 Batch Mode
You can download and run several stimulus files one after the other in the Batch mode.
The first file in the list is downloaded and started directly after the download, or started
manually with the software or hardware controls, or started on a trigger. After the first
file has been run, the second file in the list is downloaded, and so on.
Triggering a sequence of stimulation protocols
The Batch mode is useful if you want to start a sequence of different stimulation protocols
one after the other on the same trigger (Trigger 1). Please make sure that you have assigned
all channels to Trigger 1 in the Trigger Settings dialog box. You set up the protocols and save
them as separate stimulus files. Then, you set up a batch file with a list of the desired stimulus
files.
 The first trigger event starts the first file in the list.
 When a file has been completed, the next file in the list is downloaded automatically.
 When a trigger event occurs after the file has been run, the next file is started.
 When a trigger event occurs during the run of a file, the run is stopped, and the next file
in the list is downloaded. The next trigger event starts the next file.
 Deselect the option Start STG after Batch Download on the Settings menu if you want
to start the protocols on a trigger or manually with the software or hardware controls.
If the option Start STG after Batch Download on the Settings menu is selected,
the STG starts each file directly after the download without waiting for a trigger event.
As an alternative to the Batch mode, you can also use separate trigger inputs to trigger
separate output channels or separate stimulus files. This way, you can trigger both different
pulse protocols on separate channels. See chapter "Triggering Stimulation" for more details.
Note: Only Trigger 1 is available for triggering in Batch mode. Do not use any other trigger
input.
Splitting up stimulation protocols to circumvent the memory limitation
If the option Start STG after Batch Download on the Settings menu is selected, the STG
starts each file directly after the download, which is only useful in the (unlikely) case that you
need to circumvent the memory limitation of the STG. Split up your pulse protocol into several
stimulus files and run them in Batch mode.
Setting up a batch file
You have to set up a batch file (.stb) first, which lists the full path of all files that you like to
download as a batch. The batch file has to be exactly in the following format. This example
is a batch list with three different pulse protocols. Replace the file paths with the correct path
of the files of your choice.
